Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO)
follow the safety tips below.
Do not run the engine in a closed garage or in confined
areas any longer than needed to move your vehicle in or
out of the area.If it is necessary to sit in a parked vehicle with the engine
running, adjust your heating or cooling controls to force
outside air into the vehicle. Set the blower at high speed.WARNING!
If you are required to drive with the deck lid / liftgate
open, make sure that all windows are closed, and the
climate control blower switch is set at high speed.
DO NOT use the recirculation mode.

Using HomeLinkt
To operate, simply press and release the programmed
HomeLinktbutton. Activation will now occur for the
trained device (i.e., garage door opener, gate operator,
security system, entry door lock, home/office lighting,
etc. The hand-held transmitter of the device may also be
used at any time.
Reprogramming a Single HomelinktButton
To reprogram a channel that has been previously trained,
follow these steps:
1. Turn the ignition switch to the ON/RUN position.
2. Press and hold the desired HomeLinktbutton until
the indicator light begins to flash after 20 seconds.Do not
release the button.
3.Without releasing the button,proceed with Program-
ming HomelinktStep 2 and follow all remaining steps.
GATE OPERATOR/CANADIAN PROGRAMMING
Canadian radio frequency laws require transmitter sig-
nals to time-out (or quit) after several seconds of trans-
mission ± which may not be long enough for HomeLinkt
to pick up the signal during programming. Similar to this
Canadian law, some U.S. gate operators are designed to
time-out in the same manner.
It may be helpful to unplug the device during the cycling
process to prevent possible overheating of the garage
door or gate motor.
If you are having difficulties programming a garage door
opener or a gate operator, replace ªProgramming
HomeLinktº Step 3, with the following:
3. Continue to press and hold the HomeLinktbutton
while you press and release - every two seconds
(ªcycleº) your hand-held transmitter until HomeLinkt

Equipped
With the Three Zone Basic Temperature Control System,
each front seat occupant can independently control the
Heating, Ventilation, and Air Conditioning (HVAC) op-
erations coming from the outlets on their side of the
vehicle.

HEADLINER Mode
Air comes from the outlets in the headliner. Each of
these outlets can be individually adjusted to direct
the flow of air. Moving the air vanes of the outlets to one
side will shut off the airflow.
SUMMER OPERATION
The engine cooling system in air conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A 50% solution of ethylene
glycol antifreeze coolant in water is recommended. Refer
to section 7, ªMaintenance Proceduresº, of this manual
for proper coolant selection.
WINTER OPERATION
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is function-
ing properly and the proper amount, type, and concen-
tration of coolant is used. Refer to section 7,ªMaintenance Proceduresº, of this manual for proper
coolant selection. Use of the air RECIRCULATION mode
during winter months is not recommended because it
may cause window fogging.
VACATION/STORAGE
Anytime you store your vehicle, or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in the
fresh air and high blower setting. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
WINDOW FOGGING
Vehicle windows tend to fog on the inside in mild rainy
or humid weather. To clear the windows, select DE-
FROST or MIX mode and increase the front blower
speed. Do not use the RECIRCULATION mode without
A/C for long periods, as fogging may occur.

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust the
inside and outside mirrors, fasten your seat belt, and if
present, instruct all other occupants to buckle their seat
belts.
WARNING!
NEVER leave unattended children alone in a vehicle.
Leaving children in a vehicle is dangerous for a
number of reasons. A child or others could be seri-
ously or fatally injured. Don't leave the key in the
ignition. A child could operate power windows,
other controls, or move the vehicle.
WARNING!
DO NOT leave animals or children inside parked
vehicles in hot weather. Interior heat build-up may
cause serious injury or death.
WARNING!
Be sure to turn off the engine and remove the key
from the ignition switch if you want to rest or sleep
in your car. Accidents can be caused by inadvertently
moving the gear selection lever. Accidents can also be
caused by pressing the accelerator pedal. This may
cause excessive heat in the exhaust system, resulting
in overheating and vehicle fire, which may cause
serious or fatal injuries.
